Title: Differential reference control unit for anti-slip control and choke protection
Inventor: MURPHY JOHN T
IPC: B60T8/1763
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To obtain a braking control system which provides braking control for anti-slip control and choke protection by utilizing a differential reference control unit for anti-slip control/choke protection. SOLUTION: This differential reference control unit can estimate both wheel speed and vehicle speed based on input from a common wheel speed sensor. In order to eliminate a noise effect on the vehicle speed, the differential reference control unit estimates the wheel speed and the vehicle speed by executing parallel processing utilizing the two identical processing function. Either one of the estimated wheel speed and the vehicle speed is deducted by the other, a differential output indicating a slipping speed is provided thereby. Individual processings differ only in independent parameter induced from the physical- constant. Noises on the wheel speed are thus introduced to both of the processings, and is made to be void when a slipping speed is obtained when the result of the processing is deducted.

Title: Cleaning tool
Inventor: FUJITANI MASAO
IPC: A47L13/256
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To improve collection efficiency by expanding a collection area by forming the bottom surface of a support tool as the curvature part projecting in the central part and curving by forming a gentle arc toward the cleaning directional both end parts. SOLUTION: The bottom surface of a support tool 2 being a cleaning tool main body forms the curvature part 8 smoothly projecting downward in the central part 9 and curving by forming a gentle projecting circular arc toward the short part 10 in the cleaning direction A and the end part 11 in the cleaning direction B with continuing from there. When the support tool 2 is pushed in the arrow A direction on the floor 12 by gripping a handle 7, the wiping-out surface 3 of a cleaning material 1 collects and catches dirty things such as dust and dirt on the floor 12. When force is applied at that time, the arrow A directional end part 10 side is strongly pressed on the floor 12, so that the part being in contact with the floor 12 moves to the central part 9 side from the end part 10 as the force is reduced.  The wide area of the wiping-out surface 3 is used as much as possible in this way similarly when the floor is cleaned in the arrow B direction by putting the handle 7 in a (7') attitude shown by a two-dot chain line. That is, a dirty thing collection area is expanded.

Title: Treatment of olefin polymer with peroxide
Inventor: HUBER KARL
IPC: C08F255/02
Filed: 1999-11-19
Abstract: PROBLEM TO BE SOLVED: To simply and safely impart good properties, especially, good film properties to an olefin polymer by treating a microparticulate polymer at a specified temperature by feeding it together with di-tert-butyl peroxide into an extruder in an inert gas atmosphere. SOLUTION: An olefin polymer formed from the homo- or co-polymerization of ethylene or propylene and having a specific surface area of 0.2-25 m2/g and a mean particle diameter of 100-5,000 μm is fed into the hopper of an extruder directly from the polymerization step without being passed through a cooling step, and the temperature of the polymer during feeding is 55-110 deg.C. The ratio of the di-tert-butyl peroxide to the olefin polymer is in the range of 1:100,000 to 1:500. The peroxide is continuously fed into the hopper, while its feed pipe is kept immersed in the polymer in the hopper, and the feed is treated by means of a twin-screw extruder. The peroxide treatment gives a polypropylene having a melt flow rate increased by at least 5% as measured at 230 deg.C under a load of 2.16 kg.  The treated polymer is desirable in the production of moldings, films, fibers, and nonwoven fabrics.

IPC: B08B3/10
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To provide a method and device for cleaning, with high efficiency, wherein problem of waste liquid disposal does not occur by reducing the amount of an organic solvent and recovering cleaning liquid for reuse. SOLUTION: An inner tank 501 of a cleaning tank is filled with pure water, an organic solvent such as isopropyl alcohol, and such cleaning/removing agent as alkali metal salt halide as desired and ozone is dissolved in the cleaning fluid in advance after the ozone generated by an ozone generator is supplied to a porous body provided in the inner bath 501. A wafer W, wherein a resist sticks to the surface of it is submerged in the washing liquid where ozone dissolves and permeation into the resist, is allowed under a permeating force of the cleaning fluid itself and ozone for a while, for swelling of the resist. After that, an ultrasonic wave vibrator 504 provided at an outer vessel 503 of the cleaning bath is actuated to generate ultrasonic waves.  The ultrasonic wave promotes permeation of the cleaning fluid into the resist and swelling of the resist, resulting in releasing and removing of the resist from the surface of a wafer W as resist film pieces. The cleaning liquid after use is easily recycled by filtering with a filter.

Filed: 1999-12-31
Abstract: PROBLEM TO BE SOLVED: To provide a method for synthesizing a great number of carbon nano- coils from hydrocarbon by using an adequate catalyst. SOLUTION: This method of manufacturing the carbon nano-coil, which is obtained by making carbon atoms grow into a spirally winding structure and has 1,000 nm or smaller outside diameter, comprises arranging an indium-tin- iron-based catalyst inside a reactor, heating the vicinity of the catalyst to such a temperature or higher that the hydrocarbon to be used as a starting material is decomposed by the catalyst and making the gaseous hydrocarbon pass through the reactor to contact with the catalyst so that the carbon nano-coil grows on the catalyst surface while decomposing the hydrocarbon in the vicinity of the catalyst. The catalyst can be made by forming an iron thin film on the surface of a composite catalyst of indium oxide and tin oxide. An ITO substrate available on the market can be used as the catalyst and therefore the carbon nano-coil can be mass-produced at a low cost.

Filed: 1990-12-25
Abstract: PURPOSE:To enable vibration, deformation, and contour line to be visible and achieve a real-time analysis by recording a deformed object in a hologram consecutively. CONSTITUTION:Beam diameter of a laser beam is expanded by a collimator 2a and a light which is transmitted through a half mirror 4a is divided into two portions. One of the divided light is a reference light and the reflected light is emitted on an object 9a and the reflected light is focused at a lens 6a and is an object light arriving at a writing surface of a high-resolution space light modulator(SLM) 7a. When the writing pulse is applied to the SLM 7a, an interference fringe between the reference light and the object light is recorded in the SLM 7a. Also, when the interference fringe is recorded after the object 9a is deformed or is moved, an interference hologram is obtained. A reading-out light through prisms 3a-3c is emitted from a polarization beam splitter(PBS) 5a to a reading-out surface of the SLM 7a and a reflected diffraction light is reflected by the PBS 5a and then its image is formed on a CCD array 8a by a lens 6b.
